Abstract
In a graphics processing pipeline, a primitive depth sorting stageis arranged prior to the rasterization stageand rendering stage. The primitive depth sorting stageoperates to sort successive sub-sets of primitives in a stream of primitivesreceived by the graphics processing pipelinebased on their depth values. The so-sorted primitives are then output from the primitive depth sorting stagein their sorted depth order to the rasterizer. This makes the depth test stagesof the graphics processing pipelinemore efficient in their hidden surface removal operations, because the primitives entering the rasterizerwill be in depth order.
